METHOD AND SYSTEM FOR CONFIGURING UPSTREAM FORWARD ERROR CORRECTION FLOWCHART

摘要

The invention discloses a method for configuring upstream Forward Error Correction (FEC) flowchart. The method includes following steps: an Optical Line Terminal (OLT) detects the Bit Error Rate (BER) of uplinks in real time, and configures an upstream FEC flowchart based on whether the BER reaches a preset condition. An OLT is also disclosed by the invention. The OLT includes a detection module, which is set to detect the BER of uplinks in real time, and a configuration module, which is set to configure an upstream FEC flowchart based on whether the BER reaches a preset condition. With the invention, dynamically configuring the upstream FEC function of an Optical Network Unit (ONU) in real-time is enabled, and the upstream bandwidth utilization rate can be improved maximally.
